Article
For the deep impact project, a myriad of fault protection (FP) monitors, symptoms, alarms and responses is engineered into the spacecraft FP software, common and yet custom to the flyby and impactor mother-daughter spacecraft. Device faults and functional faults are monitored, which are mapped 1-to-n into FP symptoms, per instance of the fault. Sym...

While the Cassini spacecraft telemetry design had taken on the new approach of 'packetized telemetry', the AACS (Attitude and Articulation Subsystem) had further extended into the design of 'mini-packets' in its telemetry system. Such telemetry packet and mini-packet design produced the AACS Telemetry Dictionary; iterations of the latter in turn pr...

The software engineering design of the Flight Software Memory Tracker (FMT) "Tool" is discussed in this paper. FMT is a ground analysis software set, consisting of "utilities" and "procedures", designed to track the flight software, i.e., "images" of memory load and updatable parameters of the computers on-board the Cassini spacecraft. FMT is imple...
Article
The arduous task of tracking multiple flight software images, across redundant on-board processors / recorders and across time, has been automated and systematized via the use of a unified Flight Software Memory Tracker (FMT) Tool. FMT was developed as part of JPLÕs Multimission Spacecraft Analysis System, and was customized for the Cassini spacecr...
Article
Mission operations for the Mars Observer (MO) Project at the Jet Propulsion Laboratory were supported by a variety of ground data processing software and analysis tools. Some of these tools were generic to multi-mission spacecraft mission operations, some were specific to the MO spacecraft, and others were custom tailored to the operation and contr...
